    This is the load-bearing assertion for the entire build pipeline.
    If openssl-sys is in the wheel-build resolution graph, every
    Linux/macOS surface that builds from source needs system OpenSSL
    + perl modules + pkg-config — and we've spent five hot-fixes
    chasing whichever combination of perl modules / OpenSSL versions
    / pkg-config paths was missing in each manylinux/Dockerfile/
    devcontainer surface. The cleanest fix is to NOT depend on
    OpenSSL at all.

    fastembed exposes `hf-hub-rustls-tls` and
    `ort-download-binaries-rustls-tls` features that replace its
    default `native-tls` path. With `default-features = false` plus
    those rustls features enabled in headroom-core, our entire build
    tree uses rustls and no crate pulls openssl-sys.

    This test runs `cargo tree` (so it actually exercises the
    resolved feature graph, not just declared Cargo.toml features).

    `matrix.os == 'ubuntu-latest' && matrix.target == 'x86_64-unknown-linux-gnu'`
    — the literal `'ubuntu-latest'` no longer matched. Sdist never
    built, `release-assets/*.tar.gz` was empty, and the create-release
    job failed `gh release upload release-assets/*.tar.gz` with
    "no matches found".

    The fix is to key the conditional on `matrix.target` only — sdist
    is platform-independent, so any single matrix row is a fine host.
    `target` is more semantically meaningful than `os` here AND is
    decoupled from any future host-runner rename.

    This test pins the `target`-only conditional so a future "let's
    add `os` back to the conditional for clarity" refactor will fail
